I figured nothing was using it these days and it was a complete waste. If tracker uses atime, maybe I'll get more worried. But if it uses mtime, I'm not.
I've found atime useful in several cases. If you are doubting about a configuration file being read or not by an application, you just check the atime before and after running it (way easier than strace). If you are investigating what a suspect script or confused user has just done, you can find for recent atime. After it took years to go back from noatime to a weak relatime, we are now going to lose it completely again. Did any filesystem developer ever think about storing atime in a different way, instead of usual inode metadata? Maybe a dedicated journal of overriding atime entries (column based DB vs inode's row based DB) to cope with "access many files" patterns. And what happened to "lazytime"? It sounded like a great approach.
